Integrated Class-D Amplifier

In this paper an integrated stereo single-ended class D amplifier is presented. The amplifier is capable of delivering 2x100W in two 4? loads at a supply voltage of 60V. The amplifier has been realized in an SOI-based BCD technology. A second order feedback loop is used to supress supply ripple and on-idealities in the output stage. In order to be suited for mass production practical issues such as robustness and EMC have been addressed.
